NHTSA ends 14-month Waymo self-driving probe no systemic issues identified

The U.S. National Highway Traffic Safety Administration (NHTSA) has concluded a 14-month investigation into Alphabet Inc.’s Waymo autonomous vehicles following scrutiny of 22 incidents involving minor collisions and unexpected behavior by the self-driving robotaxis. The probe, initiated in May 2024, reviewed allegations that Waymo vehicles violated traffic rules or exhibited erratic actions, such as sudden stops and lane changes. NHTSA announced its decision to terminate the inquiry in July 2025, stating no systemic safety issues were identified and highlighting Waymo’s proactive measures to address concerns through two voluntary recalls [1][2][3]. The agency’s evaluation of corrective actions, including software updates to improve obstacle detection, led to the determination that further regulatory intervention was unnecessary [4].

Waymo’s response included recalls for issues like collisions with utility poles and difficulties navigating construction zones. The first recall in early 2024 followed an incident involving a pole, while the second, in May 2025, updated systems to better detect barriers and road gates. NHTSA emphasized that multiple incidents involved collisions with clearly visible objects, which a competent driver would typically avoid [5]. The agency also noted Waymo’s ongoing technical collaboration with regulators, underscoring the importance of transparency in autonomous vehicle development [6].

The closure of the investigation represents a pivotal moment for Waymo, which operates over 1,500 autonomous vehicles across U.S. cities and plans to expand to Atlanta, New York, Miami, and Washington, D.C. via partnerships and direct rollouts. While NHTSA’s decision signals regulatory confidence in Waymo’s safety protocols, it also reflects broader challenges in integrating self-driving technology into complex urban environments. Analysts suggest that the agency’s approach—prioritizing data analysis and voluntary compliance over punitive measures—aligns with a trend of balancing innovation with public safety [7]. This outcome may encourage other autonomous vehicle developers to adopt similar strategies to navigate regulatory scrutiny while maintaining operational momentum [8].

For the industry, the resolution highlights the critical role of proactive problem-solving in addressing public and regulatory concerns. Waymo’s ability to resolve technical issues through recalls and software updates demonstrates a model for managing risks associated with emerging technologies. However, the probe also underscores the need for continuous refinement of AI-driven safety systems, as minor incidents can erode public trust and trigger regulatory scrutiny. NHTSA’s emphasis on data transparency and corporate accountability sets a precedent for future investigations, reinforcing the expectation that developers will collaborate closely with regulators to address evolving challenges in autonomous transportation [9].

Waymo’s expansion plans face hurdles beyond technical compliance, as seen in Boston, where local officials are reviewing legislation to govern autonomous vehicles. While the company has not confirmed a timeline for entering the Boston market, its cautious approach aligns with the broader industry’s recognition that public acceptance remains a key barrier to widespread adoption. The closure of the NHTSA investigation does not eliminate these challenges but provides a foundation for continued growth in a sector still navigating regulatory and societal complexities [10].
